Anatomic variations of the cystic duct and its junction with the common hepatic duct

: The ductus cysticus is variable in the length, position and the site where it enters the ductus hepaticus communis--the cystohepatic junction. The investigations were carried out on 100 livers (50 anatomical preparations and 50 patients) adults of both sexes, randomized trial. Main methods of the research were: anatomical macrodissection and analysis of the clinical radiograms. The ductus cysticus were present as: flat--down course in 70%, flat--horizontal course in 2%, flat--ascendant course in 4%, curved in the shape "J" in 10%, curved in the shape "S" in 12% and curved in the shape "U" in 2%. The cystohepatic junction shows variations in topographic zones.
